Changelog

Version 0.2.0

Many more printers: five Elegoo printers (Saturn 4, Saturn 4 Ultra, Saturn 3 Ultra, Mars 4 Ultra, Mars 5 Ultra), the Creality Halot-One, Halot-Sky and Halot-Mage, the Phrozen Sonic Mini 8K and 28 more Anycubic printers, slicing to `.goo`, `.ctb`, `.cxdlp` and `.cxdlpv4` files. Can't find yours? Ask for it, or submit a machine you made, from the machine select.
Open 3MF and OBJ files as well as STL; a file with several objects puts each on the plate as its own model.
Open a sliced print file to check its layers and settings before printing.
Hollow a model in the new Hollow tab, with drain holes where you click. Copal shows the resin a model traps and warns of hollows that act as suction cups as the plate lifts.
A model made of several solids pushed into each other, such as a base with its decorations, is merged into one solid when it loads, so it checks, repairs and prints as one body.
Support presets of your own beside Light, Medium and Heavy, and a raft that follows the model's outline.
Select several models at once to move or delete them together, and use keyboard shortcuts close to Lychee Slicer's: press ? to see them all.
Install Copal as an app and keep using it offline once it has loaded.
Copal now lives at copalslicer.com. It asks before measuring visits with Google Analytics, and you can change your choice on the privacy page.

The first preview: open STL models from the file picker or by dropping them on the plate.
Every model is checked for defects as it loads, and Repair fixes them with one click.
Move, turn, scale, mirror and lay models flat, duplicate them and arrange the plate, with undo and redo.
Supports: generate tree or straight supports, add, move, paint and fill them by hand, and stand the model on a raft.
Slice to a .pm4u file for the Anycubic Photon Mono 4 Ultra, with the print time, resin use and cost.
Machine and resin profiles of your own, imported and exported as files.
Projects saved in the browser or exported to a file.
A What's new dialog after each update, every version's changes on the Changelog page, and a notice when a newer version is deployed.
